In the eighteenth century, 30 years, in order to adapt the processing watches, bicycles, sewing machines and other parts of firearms after hardening, the UK, Germany and the United States were developed using natural abrasive wheel grinder. These grinders are readily available at the time of installation of the machine, such as lathes, planers and other top grinding restructuring of internal grinder, their structure is simple, low stiffness internal grinder specification, easy to produce vibration grinding operations require workers to have a very skills to grind high precision parts. 1876 ??exhibited at the Paris Exposition of the American Brown - universal cylindrical grinder manufactured by Sharp, is the first modern basic characteristics of the mechanical grinder. It workpiece headstock and tailstock mounted reciprocating table, box-shaped bed increases the stiffness of the machine, and with internal grinding attachment. In 1883, the company made grinder mounted on the column, table for reciprocating surface grinder. After 1900, the development and application of artificial abrasive hydraulic transmission, the development of grinders have a great role in promoting. With the development of modern industry, particularly the automotive industry, a variety of different types of grinders have been published. Such as the early 20th century, has developed a cylinder block machining inner planets grinder, crankshaft grinder, camshaft grinder and grinder with magnetic chuck piston rings and so on. Automatic measuring device in 1908 began to apply to the grinder. To 1920, the centerless grinder, double-end grinders, roll grinders, rail grinding, honing and super finishing machines, etc. have been made to use; the 1950s appeared to make mirror grinding precision cylindrical grinder; 60s appeared at the end of wheel speed of 60 ~ 80 m / sec high-speed grinder and large depth of cut, creep feed grinding surface grinding machine; the 1970s, the use of digital microprocessor control and adaptive control techniques in the grinder has been widely applications. Grinder manufacturers, surface grinder manufacturers, large grinding machine price, gantry grinder manufacturers, grinding machine manufacturers, used cylindrical grinding machines - CNC Hengda, I believe your choice, absolutely nothing wrong. With the rapid industrial development of society, surface grinder also showed the following trends. A: High-speed, complex, high-precision, high rigidity surface grinder is still the main theme of development, but there are new changes. Complex from the original composite and composite into consideration mainly from practical and efficient. II: milling and EDM compound, from a functional point of view, complex surface grinder highly targeted, for certain parts to consider, from the accuracy point of view, repeat positioning accuracy of the machine has been everywhere, from the spindle speed run , speed is not a proprietary low-power characteristics of the spindle, from the rigid point of view, there have been 60HRC hardness machinable materials processing center. Three: The modular design in machine tool manufacturing has been widely used, the lateral series, portrait series, the whole series, cross-series modular design reflected most vividly in the exhibits. Four: automatic concept has changed the traditional automatic machine is inside the plane with a pneumatic or hydraulic robot to achieve automatic loading and unloading workpieces grinder manufacturers, but there are more than 10 units or more machining centers and turning on exhibition center, using the true meaning of the multi-joint robot tandem to achieve the maintenance of internal grinder unloading workpieces, including the completion of parts stacked. Five: to increase the scope of control, flexibility, strengthening group lines, while significantly reducing Auxiliary machinery. Six: increasing environmental requirements, the exhibits, the vast majority of machine tool products are fully enclosed in the casing, absolutely no chips or cutting fluid splashing phenomenon, on the other hand, a large number of industrial cleaning machines and presentation of cutting fluid processor systems, while also reflecting the modern manufacturing increasing demands for environmental protection.
